I've seen that bug before.  That's a change which got reverted, or at
least, the default behavior was returned to the previous norm.

Debian's /etc/systemd/logind.conf has

#KillUserProcesses=no

which indicates that the default is for this "kill everything the user
left running" setting to be disabled, as it was before the controversial
change.

I think this is a dead end for this particular question, because it's
an all-or-nothing setting.  Either *all* background processes that the
user creates get nuked when the user logs out, or *none* of them do.  There
doesn't appear to be a way to "mark" particular processes for reaping
while leaving the rest alone.

Maybe some other part of systemd offers more flexibility, but if so, I
don't know what part it would be.  I'm still waiting to see an actual
user-friendly *document* that describes how to use systemd.
